Button not visible when keyboard is shown

I am trying to implement a functionality where the button below EditText moves up when the keyboard is shown, this is a login fragment and I would like to have this functionality similiar to what Instagram has. Right now, when keyboard is pressed, the EditText moves up but the button is hidden. I am attaching the xml below for the same.

Use ConstraintLayout to position the button to the bottom of the screen and then add.
<activity
android:name=".activity"
android:windowSoftInputMode="adjustResize"
android:exported="false" />
...in the activity that would host that Fragment's layout.
Note
The button should be layout in this manner:
<androidx.constraintlayout.widget.ConstraintLayout>
<Button
android:id="#+id/finish"
android:layout_width="match_parent"
android:layout_height="wrap_content"
... />
</androidx.constraintlayout.widget.ConstraintLayout>
... but right now in your code, I can see the button inside a LinearLayout. Change the layout to make the button be positioned at the bottom of a ConstraintLayout and make that ConstraintLayout the parent of that button. The ConstraintLayout should also fill the whole screen.
Edit:
When you use windowSoftInputMode="adjustResize the system positions the element at the bottom of the screen on top of the keyboard and makes your layout shrink in size. So you need to attach a ScrollView to make your layout scrollable.
Like this:
<androidx.constraintlayout.widget.ConstraintLayout
android:layout_width="match_parent"
android:layout_height="match_parent"
...>
// Position this scrollView to fill the entire screen
<ScrollView
android:layout_width="0dp"
android:layout_height="0dp"
...>
// This scroll view layout would contain all your other layout views
</ScrollView>
<Button
android:id="#+id/finish"
android:layout_width="match_parent"
android:layout_height="wrap_content"
... />
</androidx.constraintlayout.widget.ConstraintLayout>
Working principle
The button should not be a child view of the ScrollView, it should be a child view of the root view, which is a ConstraintLayout that fills the screen, then the button is positioned to the bottom of the root view. The bottom of the ScrollView should be positioned to the top of the Button. That way, the child views of the ScrollView is scrollable and the button stays on top of the keyboard.

Go to your AndroidMenifest File, Inside you <activity> tag put android:windowSoftInputMode = "adjustpan" it would handle the view after showing up keyboard. if adjustpan doesn't work, there are more property, use one respect to your need.
example:
<activity
android:name=".YourActivityName"
android:windowSoftInputMode="adjustPan"
android:exported="false" />

Android Studio renders it in this way:
And this is what I want to have in my Dialog.
BUT:
On physical device and on emulator it looks different than in Android Studio:
My question is: how to place "Filter" title on the left, and make the location EditText matching the parent (in the working app)?

What everybody else said is correct, keeping your layout flat is good for both performance and for these situations where you want to quickly figure out why isn't the layout being laid out the way you wanted it ;)
Try this :
<androidx.constraintlayout.widget.ConstraintLayout xmlns:android="http://schemas.android.com/apk/res/android"
xmlns:app="http://schemas.android.com/apk/res-auto"
android:layout_width="match_parent"

android:paddingHorizontal="15dp"
android:paddingVertical="10dp">
<TextView
android:layout_width="0dp"
android:layout_height="wrap_content"
android:gravity="start"
android:text="Filter"
app:layout_constraintBottom_toBottomOf="#id/bt_reset"
app:layout_constraintEnd_toStartOf="#id/bt_reset"
app:layout_constraintStart_toStartOf="parent"
app:layout_constraintTop_toTopOf="#id/bt_reset" />
<com.google.android.material.button.MaterialButton
android:id="#+id/bt_reset"
style="#style/Widget.MaterialComponents.Button.OutlinedButton"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:text="RESET FILTERS"
app:layout_constraintEnd_toEndOf="parent"
app:layout_constraintTop_toTopOf="parent" />
<TextView
android:id="#+id/tv_distance_title"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:text="Distance range"
app:layout_constraintBottom_toBottomOf="#id/tv_distance_result"
app:layout_constraintStart_toStartOf="parent"
app:layout_constraintTop_toTopOf="#id/tv_distance_result" />
<TextView
android:id="#+id/tv_distance_result"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:layout_marginTop="15dp"
android:background="#ddd"
android:gravity="center"
android:paddingHorizontal="18dp"
android:paddingVertical="3dp"
android:text="0 km - 500km"
android:textColor="#333"
app:layout_constraintEnd_toEndOf="parent"
app:layout_constraintTop_toBottomOf="#id/bt_reset" />
<com.google.android.material.slider.RangeSlider
android:id="#+id/slider_distance"
android:layout_width="match_parent"
android:layout_height="wrap_content"
android:stepSize="1.0"
app:labelBehavior="gone"
app:layout_constraintTop_toBottomOf="#id/tv_distance_result" />
<TextView
android:id="#+id/tv_location_title"
android:layout_width="match_parent"
android:layout_height="wrap_content"
android:text="Location"
app:layout_constraintTop_toBottomOf="#id/slider_distance" />
<EditText
android:id="#+id/et_location"
android:layout_width="match_parent"
android:layout_height="wrap_content"
android:hint="test"
app:layout_constraintTop_toBottomOf="#id/tv_location_title" />
<Button
android:id="#+id/bt_cancel"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:layout_marginTop="10dp"
android:layout_marginEnd="20dp"
android:backgroundTint="#ccc"
android:text="CANCEL"
android:textColor="#color/colorBlack"
app:layout_constraintEnd_toStartOf="#id/bt_save"
app:layout_constraintTop_toBottomOf="#id/et_location" />
<Button
android:id="#+id/bt_save"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:layout_marginTop="10dp"
android:layout_marginEnd="20dp"
android:text="save"
app:layout_constraintEnd_toEndOf="parent"
app:layout_constraintTop_toBottomOf="#id/et_location" />
</androidx.constraintlayout.widget.ConstraintLayout>

I changed inner ConstraintLayouts into LinearLayouts and used weights. I also used this trick to fill space between e.g. "Filter" title and "reset filters" button.
There was also an issue with ll_location LinearLayout - it didn't match the parent.
I replaced:
<LinearLayout
android:id="#+id/ll_location"
android:layout_width="match_parent"
android:layout_height="wrap_content"
app:layout_constraintTop_toBottomOf="#id/ll_distance_ext"
android:orientation="vertical">
<!-- content -->
</LinearLayout>
into:
<LinearLayout
android:id="#+id/ll_location"
android:layout_width="0dp"
app:layout_constraintStart_toStartOf="parent"
app:layout_constraintEnd_toEndOf="parent"
android:layout_height="wrap_content"
app:layout_constraintTop_toBottomOf="#id/ll_distance_ext"
android:orientation="vertical">
<!-- content -->
</LinearLayout>
And then it worked.
The reason why I don't want to use flat layout (why I use nested layouts) is that IMHO the flat layout makes the code more difficult to maintain.
When you have Views splited into groups you can easily replace them, no matter how many View there are in a group.

How to change animateLayoutChanges order?

I have used animateLayoutChanges in my layout, I have 3 child that second visibility is gone, so third is in first below. When I click the first child, I change second visibility to visible, vice versa.
When I see the animation order look bad, I want the animation run parallel when it is show and pull down or it is hide and pull up.
There is the gif.
Animation Gif
All I want is the animation when it is hide and pull down or show and pull up is run parallel.
There is my xml

We got really bad performance when scrolling through the RecyclerView, and everything work just fine if I change item layout from a ConstraintLayout to a traditional layout (Nesting 4 or 5 layers). What can we do about this?

I have used ConstraintLayout as item layout of recyclerview, it scrolls smoothly. I think there is no problem of ConstraintLayout, but make sure that you should not call myAdapter.notifyDataSetChanged() in adapter class. It will make your app slow UI rendering.
Refer this Android document for Slow rendering

Set linearLayout margin

I need to fill a LinearLayout (child of a ScrollView) with dynamic TextViews.
The problem is that, in my app, the position where the scroll starts is not defined (it changes dynamically while using the app) and I think I've resolved this with layout_constraintTop_toBottomOf.
The main problem is that I need the ScrollView to end at 90dp from the bottom. But I cannot do that with margins (as in my code below) cause it ignores them.
I've also tried padding but doesn't work too.
This is my solution that doesn't work:
<ScrollView
android:id="#+id/scroll_seguiti"
android:layout_width="match_parent"
android:layout_height="wrap_content"
android:layout_marginEnd="10dp"
android:layout_marginStart="10dp"
android:layout_marginTop="10dp"
android:layout_marginBottom="90dp"
app:layout_constraintEnd_toEndOf="parent"
app:layout_constraintStart_toEndOf="parent"
app:layout_constraintTop_toBottomOf="#id/scroll_view">
<LinearLayout
android:id="#+id/linear_view_seguiti"
android:layout_width="match_parent"
android:layout_height="wrap_content"
android:paddingBottom="90dp"
android:orientation="vertical">
</LinearLayout>
</ScrollView>
I really need that margin cause at the bottom there are some buttons.

you need to set margin only for scroll view. Remove the margin from the linear layout.
Add full viewport: true for scroll view.
